About this trial

The goal of this clinical trial is to learn if transcutaneous auricular vagus nerve stimulation (taVNS) works to treat motor and neurocognitive deficits after ischemic stroke when applied within 30 days after onset of stroke.

The main questions it aims to answer are:

* Does tVNS improve motor deficits measured by the Fugl-Mayer assessment after ischemic stroke? * Does tVNS ameliorate stroke-related cognitive impairment? Researchers will compare tVNS to a placebo (sham stimulation, i.e. an electrode is fixed on the ear without applying electrical impulses ) to see if tVNS works to treat motor and cognitive deficits after stroke .

Participants will:

* Receive tVNS or sham stimulation for 30 minutes 5 days a week during 5 weeks after ischemic stroke * Receive smotor and cognitive training during the tVNS or sham stimulation * Will take part on a standardized stroke rehabilitation program during the 5 weeks in a rehabilitation clinic.
